Alstroemeria ligtu seedlings

Shirley's right about ligtu and how they pull themselves deep..
Anecdotes:
a) in one of our sand beds after years of trying we find that we
cannot get a shovel deep enough to remove all of the rhizome pieces
b) even in a mostly clay soil seedlings have managed to go .8 to 12
inches deep.
c) Years ago the UC Berkeley Botanical Gardens wanted to remove a
large section devoted to ligtu and I'm not sure whether they ever
succeeded entirely even with their expert staff hard at it.
